Ingo Molnar d7eda6c99c x86/fpu: Clean up parameter order in the copy_xstate_to_*() APIs
Parameter ordering is weird:

  int copy_xstate_to_kernel(unsigned int pos, unsigned int count, void *kbuf, struct xregs_state *xsave);
  int copy_xstate_to_user(unsigned int pos, unsigned int count, void __user *ubuf, struct xregs_state *xsave);

'pos' and 'count', which are attributes of the destination buffer, are listed before the destination
buffer itself ...

List them after the primary arguments instead.

This makes the code more similar to regular memcpy() variant APIs.

No change in functionality.
